The discovery of the Higgs boson [1]}, [2]} of the Standard Model (SM)
is definitely a very important milestone in the history of particle physics.
It ends the quest of searching for the last SM particle after a long time and then further solidifies the plinth of the SM.
Although the observation of the Higgs boson ensures its existence and its role for the electroweak symmetry breaking,
more precise measurements of the Higgs boson properties are necessary for verifying the SM Higgs sector
and/or for revealing new physics beyond the SM (BSM).
